Going Beyond Predictions

Last Updated on June 7, 2016 The predictions you make with a predictive model do not matter, it is the use of those predictions that matters. Jeremy Howard was the President and Chief Scientist of Kaggle, the competitive machine learning platform. In 2012 he presented at the O’reilly Strata conference on what he called the Drivetrain Approach for building “data products” that go beyond just predictions. In this post you will discover Howard’s Drivetrain Approach and how you can use […]

Master Kaggle By Competing Consistently

Last Updated on June 7, 2016 How do you get good at Kaggle competitions? It is a common question I get asked. The best advice for getting started and getting good is to consistently participate in competitions. You cannot help but get better at machine learning. A recent post by Triskelion titled “Reflecting back on one year of Kaggle contests” bares this out. He started out as a machine learning beginner and finished up as a “master” level Kaggle competitor […]

How To Estimate Model Accuracy in R Using The Caret Package

Last Updated on August 15, 2020 When you are building a predictive model, you need a way to evaluate the capability of the model on unseen data. This is typically done by estimating accuracy using data that was not used to train the model such as a test set, or using cross validation. The caret package in R provides a number of methods to estimate the accuracy of a machines learning algorithm. In this post you discover 5 approaches for […]

How To Get Started With Machine Learning Algorithms in R

Last Updated on August 22, 2019 R is the most popular platform for applied machine learning. When you want to get serious with applied machine learning you will find your way into R. It is very powerful because so many machine learning algorithms are provided. A problem is that the algorithms are all provided by third parties, which makes their usage very inconsistent. This slows you down, a lot, because you have to learn how to model data and how […]
